Desulfurization Absorber

II. Nzvimbo nhatu Dzinoshanda dzeDesulfurization Absorber

Chinonyudza chinogona kukamurwa kuita nzvimbo nhatu dzinoshanda kubva kumusoro kusvika pasi: oxidation crystallization, absorption uye demisting zone.

(1) Nzvimbo yekucheneswa kweokisijeni (oxidation crystallization zone) inoreva dziva rekunyungudutsa remuchina unonyungudutsa mvura, uye basa rayo guru nderekunyungudutsa limestone uye oxidize calcium sulfite.

(2) Nzvimbo inonyudzwa inosanganisira nzvimbo inonyudzwa mvura, tireyi uye nzvimbo dzakasiyana-siyana dzekupfapfaidza. Kune maburi akawanda emakona asina chinhu pachikamu chimwe nechimwe chemudziyo wekupfapfaidza; basa guru remudziyo uyu nderekunyudzwa kweasidhi uye kunyudzwa kweash inobhururuka mumhepo inoyerera.

(3) Nzvimbo yekudzima ine madonhwe maviri pamusoro pechikamu chekupfapfaidza. Basa rayo guru nderekuparadzanisa madonhwe ari mugasi remvura, zvichideredza kukanganiswa kwemidziyo iri pasi pemvura uye huwandu hwemushonga unonyungudutsa mvura.

Nzvimbo yekunyudza yemuchina wekunyudza inoreva nzvimbo iri pakati pemutsetse wepakati pemuchina wekunyudza uye wechikamu chepamusoro chekupfapfaidza. Slurry yakapfapfaidzwa inosuka gasi rine sarufa munzvimbo iyi. Kureba kwakakwana kwenzvimbo yekunyudza kunoita kuti pave nechiyero chepamusoro chekunyudza. Kureba kwakakwirira, ndiko kudzikira kwechiyero chekuyerera kwepombi yekutenderera. Pasi pechinodiwa chimwe chete pachiyero chekunyudza.

Nzvimbo yekupfapfaidza yeabsorber inotsanangurwa se:

(1) Nhare yekupfapfaidza: 1.5m pasi pemuromo wepasi kusvika panzvimbo yekubuditsa mvura yemuromo wepamusoro.

(2) Nhare yekoramu yemvura: kubva panobuda mvura mumuromo wepasi kusvika pa 0.5m pamusoro pekoramu yemvura yakakwirira apo mapombi ese emvura ari kufamba.

Chinonyudza ndicho chinhu chikuru chegadziriro yekubvisa sarufa mumhepo. Chinoda nzvimbo yakakura yekubata gasi nemvura, kuita zvakanaka kwegasi, uye kurasikirwa kudiki kwekumanikidzwa. Chakakodzera kurapwa kwegasi rine simba guru. Matanho ekutanga ekuita aya anoitwa mumudziyo uyu:

① Kutorwa kwemagasi anokuvadza mukuwachisa slurry;

② Kupatsanurwa kwegasi remvura inoyerera uye slurry yekuwachisa;

③ Kusaita kuti slurry isashande zvakanaka;

④ Kuisa okisijeni yezvigadzirwa zvepakati-pakati zvekubvisa tsvina mu gypsum;

⑤ Kuumbwa kwejecha remagiyipu.

III. Kuumbwa kweMushonga Unonyudza

Chinonyungudutsa mvura chinowanzo patsanurwa kuita sirinda, nzvimbo inopinzwa negesi inobuda neflue gas. Nzvimbo inopinzwa nemhepo inobuda negesi inobuda neflue gas iri pakati pechinhu chinonyungudutsa mvura uye pamusoro pechinhu chinonyungudutsa mvura nenzira yakajairika. Sirinda inonyungudutsa mvura inogona kupatsanurwa kuita dziva remvura inobuda netsvina, nzvimbo inopfapfaidza uye nzvimbo inobvisa mvura. Dziva remvura inobuda netsvina riri pasi penzvimbo inopinzwa nemhepo inobuda netsvina, uye nzvimbo inopfapfaidza nechinhu chinonyungudutsa mvura zviri pakati penzvimbo inopinzwa nemhepo inobuda netsvina. Nzvimbo inopinzwa negesi inobuda neflue gas inogona kuva nzvimbo inobuditsa mvura yakananga kana nzvimbo inobuditsa mvura yakatwasuka.

Nzvimbo yekupfapfaidza yakajairika ine machira ekupfapfaidza nema nozzles nezvimwe zvishandiso. Zvichienderana nemaitiro ekubvisa sarufa, nzvimbo yekupfapfaidza yemamwe ma absorbers ichavewo netireyi, tsvimbo dzeVenturi nezvimwe zvishandiso.

IV. Zvinodiwa pakugadzira Absorber

(1) Chiyero checalcium-sarufa hachifanirwe kupfuura 1.05.

(2) Pakushandisa mudziyo wekudzivirira mhepo uri mudenga, kumhanya kwemhepo inoyerera yemuchina unopinza mhepo pasi pemamiriro ekugadzira hakufanirwe kudarika 3.8m/s, izvo zvinogona kutariswa ne Coriolisfyakadereraakasanganaer.

(3) Chimiro chakabatana chedziva rine tsvina nemuviri weshongwe ndicho chinofarirwa.

(4) Nguva yekugara kwemvura inoyerera haifanirwe kunge iri pasi pemaminitsi mana, uye shongwe yesimbi yemvura haifanirwe kunge iri pasi pemaminitsi maviri nehafu.

(5) Ringi inochengetedza mvura nechivharo chemvura zvinofanirwa kuiswa panzvimbo inoungana mvura inopinza mvura inonyungudika uye madziro akamira echinonyungudika.

(6) Nzira yekupinda mugomba risina chinhu inofanira kurongwa nenzira yekupinda yakamanikana ichidzika. Kana nzira yekupinda yakataramuka yagamuchirwa, zvinofanira kuve nechokwadi chekuti nzvimbo yakaderera yegomba iri pagokora rekutanga riri pedyo nenzira yekupinda mugomba iri yakakwirira ne1.5 kusvika 2m kupfuura mwero wemvura unoshanda wegomba remvura rinopinza mvura. Nzira yekupinda mugomba remvura inogona kurongwa nenzira yekupinda yakataramuka kana yakatwasuka.

(7) Nhambwe iri pakati pezvikamu zvespray zviri pedyo zveshongwe isina chinhu yekupfapfaidza haifanirwe kunge iri pasi pe1.8m.

(8) Chikamu chepamusoro chekupfapfaidza cheshongwe isina chinhu chekupfapfaidza chinofanira kungopfapfaidza pasi chete, uye daro rakadzika kubva pachikamu chidiki chemuchina wekubvisa mvura harifanirwe kunge riri pasi pe2m.

(9) Kune mashongwe ekupfapfaidza ane matireyi ane maburi nematabulator, matireyi ane maburi nematabulator anofanira kugadzirwa nezvinhu zvinodzivirira ngura.

(10) Kana mudziyo wekudziyisa nekutsinhanisa gasi rinobuda utsi usina kuiswa, kusarudzwa kwema parameter ekugadzira akadai se empty tower flow rate, liquid-gas ratio, uye slurry solid content ye absorber inofanira kufunga nezvezvinodiwa zve desulfurization efficiency uye pesvedzero yezvinhu zvakaita sekuderedza huwandu hwemadonhwe egasi anotakurwa.

(11) Dhizaini yemuchina wekunyudza inofanira kugadziriswa zvichienderana nehuwandu hwemutoro webhoyira uye huwandu hwesarufa yemarasha.isiri yenyukireyaslurry density meterkubvaLonnmeterZvinokurudzirwa kuti utarise huwandu hwe limestone ne gypsum panzvimbo yekubuditsa mvura kuti uve nechokwadi chekuti mvura inobviswa mu sulfurization yakakwana.
